Grade 6 

In this unit, students will calculate areas of polygons by decomposing, rearranging, enclosing, and composing shapes. They will also represent polyhedra with nets and calculate their surface areas.

In this unit, students will be introduced to the concept of ratios. They will represent ratios using double number lines, tables, and tape diagrams, and use ratio reasoning to solve problems.

In this unit, students will apply ratio reasoning from Unit 2 to unit rates and recognize that equivalent ratios have the same unit rates. They  will use a variety of strategies and representations of percentages to determine missing percentages, parts, and wholes.

In this unit, students will extend what they learned about dividing whole numbers to divide fractions by fractions. They answer questions like “How many groups?” or “How many in 1 group?” They will use a variety of strategies, such as making tape diagrams, finding common denominators, and rewriting equivalent multiplication problems using reciprocals.

In this unit, students will develop and use a variety of strategies for adding, subtracting, multiplying, and dividing decimals.

In this unit, students will build on their understanding of the equal sign and use it to represent equality (or balance), at which point they can perform balanced operations to solve for unknown values and relate equivalent expressions, including those involving two variables or exponents.

In this unit, students will explore positive and negative numbers in several ways: on a number line, represented as inequalities, and on the coordinate plane. They will compare these numbers, as well as their absolute values.

In this unit, students will visualize data using dot plots and histograms, before calculating measures of center-mean and median-and measures of variability- mean absolute deviation (MAD), range, and interquartile range (IQR). They will construct box plots and interpret these measures in context, relating the shape and features of a distribution to the most appropriate measures.
